Last year, the entire Internet was delighted by Maisie Williams, Sophie Turner and Isaac Hempstead-Wright — Arya, Sansa and Bran Stark, respectively — singing their version of the Game of Thrones opening credits in a DVD/Blu-ray commentary track. Well, the season 2 Blu-ray/DVD is coming out next month, and I'm delighted to tell you the kids are back together for another commentary track, and since they've matured, they're not singing the opening theme... they're beatboxing it.
